3 Claims. (Cl. 22313) This invention relates generally to hat formingmachines and more particularly to a block or die of such machine whereindifferential pressure is applied to those portions of the structureshaping the crown and brim of the hat, respectively.

The primary object of this invention is a block or die in which thecrown forming and brim forming members are separate entities.

Another object of the invention is to so mount crown and brim formingmembers as to permit differential pressures to be applied to therespective members.

A further object of the invention is to support separate crown and brimforming members old per se on a hollow head such as shown in UnitedStates Patent No. 2,064,824.

The invention also seeks a hat forming structure suitable for use withdifferential pressures which is practical from the standpoint of ease ofmanufacture, celerity of assembly and convenience and durability in use.

These and other objects of the invention and the means for theirattainment will be more apparent from the following detaileddescription, taken in connection with the accompanying drawingillustrating one embodiment by which the invention may be realized andin which:

Figure 1 is a view in transverse section showing a block or die of a hatforming machine to which the invention is applied;

Figure 2 shows a top view of the structure of Figure 1; and

Figure 3 is a fragmentary, transverse, sectional view taken in the planeindicated by the line 33 of Figure 2 and looking in the direction of thearrows.

The invention is here illustrated as applied to the upper block of a hatforming machine but it is to be understood that it is equally applicableto either the upper or the lower block or head of such machine.

As illustrated, the upper wall 5 of the hollow head 1 is formedcentrally with a depending portion 9 formed with a vertical passage H. Abrim forming disc-like element I3 of flexible material such as rubber iscarried on the lower edge of the head by a retaining annulus l6 and isof such size and shape as to extend up- Wardly and be in contact with aspacing and positioning plate I! interposed between the dependingportion 9 and the brim forming element l3, an aperture IS in the brimforming element [3 and an aperture 2| in the plate I! registering withthe passage ll. Sealing means 23 may be disposed between portion 9 andthe plate H and is apertured, as at '25, to register with the aperturesl9 and 2|.

The dome or crown forming bag element 21 which is also of yieldingmaterial, such asrubber,

may take any shape, here shown as oval, and has formed integral with theupper edge of the wall an inwardly extending lipor flange portion 30defining an oval aperture into the interior of the bag 21 which is heldin place by the oval disc 32 having an aperture 34 registering with thepassage ll so that the element 21 is substantially a closed body withonly the aperture 34 in register with the passage H. The inner surfaceof this top wall 30 is provided with a continuous depending rib 36 whichis received in the annular groove 38 in the plate 32 adapted to retainthe parts in proper positions. As shown,

the disc 32 is formed with a thicker oval portion 39 coinciding with theinner wall of groove 38 which fits within the opening 3| and whereof itsupper surface lies flush with the top surface of the crown bag 21.

Plate 32 is held in position by bolts All shown as diametricallydisposed upon opposite sides of the passage II and passing throughregistering holes in the parts 9, I1, I3, 30 and threaded into threadedapertures in plate 32 and the heads 42 of the bolts 43 being accessiblefrom without the head 5.

Fluid, either liquid or gaseous, enters the space between the brimforming element I 3 and the dome 5 from one source (pipe 44) and entersthe crown member 21 through the pipe 46 entering passage H.

The hat die of this invention is readily assembled and disassembled. Bythe removal of the two bolts 40, the plate 32 is released, thereby alsoreleasing the crown bag 21 for removal. The plate 32 may then be removedfrom the crown bag by passing it endwise through the opening 3|. Thebrim forming member 43 is released by removing annulus It as by removingthe bolts 48. This permits access to the spacing plate I! and gasket 23.

Various modifications will occur to those skilled in the art in thecomposition, configuration and disposition of the component elementsgoing to make up the invention as a whole as well as in the selectionand combination of particular features to accomplish specific results,and no limitation is intended by the phraseology of the foregoingdescription or illustrations in the accompanying drawing except asindicated in the appended claims.

What is claimed is:

1. In a hat machine, in combination, a head member having a fluiddepending central portion formed with a passage and bolt holes onopposite sides of the passage, a disc-like brim forming element ofyielding non-metallic material formed with an aperture to register withthe passage in the head and bolt holes to register with the holes in thehead, means to secure the periphery of the brim forming element to thehead, a plate between the brim forming element and the head and formedwith an aperture to register with the passage in the head and bolt holesto register with the bolt holes in the head, sealing means between theplate and the depending portion of the head, a separate crown bag formedwith an inwardly directed lip, said lip being formed with a continuoushead on its surface, a retaining plate within the crown bag formed witha continuous groove in its upper surface to receive the bead on thecrown bag and threaded apertures to register with the aforesaid boltholes and an aperture therebetween to register with the passage andbolts in the bolt holes.

2. In a hat machine, the combination with a head member formed with afluid passage, of a brim forming element formed with a fluid aperture toregister with the fluid passage in the head, a separate crown bag formedwith an inwardly directed lip, said lip being formed with a continuousbead on its lower surface, a retaining plate within the crown bag formedwith a continuous groove in its upper surface to receive the head on thecrown bag and an aperture to register with the passage and means toretain the retaining plate in position.

3. In a hat machine, the combination with a head, of a brim formingelement, a separate crown bag formed with an inwardly directed lip, saidlip being formed with a continuous bead on its lower surface and aretaining plate within the crown bag formed with a continuous groove inits upper surface to receive the bead on the crown bag, that portion ofthe plate within the groove being of increased thickness to be receivedwithin the aperture defined by the lip.
